4VV'ILLIAM MUNTON BULLIVANI, OF LONDON, ENGLAND.

ROPENSTOPPER.

SPECIFICATION forming part of Letters Patent No. 311,565, dated February 3, 1885.

Application filed April 3, 1884. (No model.) Patented in England January 28, 1880, No. 314, and in Belgium November 21, 1882, N0. 59,631.

To all whom, t may concern.-

Beit known that I, WILLrAM MUNTON BUL- LIVANT, a subject of the Queen of Great Britain and Ireland, and residing at 72 Mark Lane, in the city of London, England, have invented certain Improvements in Rope-Stop pers, (for which I have obtained patents in Great Britain, No. 314, dated January 23, 1880, and Belgium, No. 59,631, dated November 2l, 1882,) of which the following is a speciiication.

My invention has for its object improvements in rope-stoppers. According to my said invention I construct a rope-sto pper especially suited to be used with a wire rope in the following manner:

It consists of a casting which is firmly fixed on the deck of a ship or to other suitable foundation, and this casting has two parallel sides or cheeks, between which a block is placed. This block is able to move between the cheeks both horizontally and longitudinally. rIhe rope to be held is passed along the side of the block, which is channeled (as is also the opposed cheek) to receive it, and the block is caused to nieve toward the side to nip the rope between the block and the cheek. A stout plate or cover closes in the casting at the top. toggles, or inclined legs or toggles, the other ends of which bear against the side of the casting. rIlhe block has movement imparted to it from a screw-rod attached at one end to the block, and passing at the other end through the casting, and provided outside the casting with a lever or wheel with a screw-hut, through which the screw of the rod passes, so that by rotating Athe said lever or handle the block may be caused to grip the rope running through the stopper, so that it may be retarded to any desired extent.

In order that my said invention may be most fully understood and readily carried into effect, I will proceed to describe the drawings hereunto annexed.

Figures l and 2 are plans (with the cover removed and with the cover in place, respect- The block rests against levers or' the cheek (d.

ively) of a ropestopper constructed in accordance withmy invention. Fig. 3 is :a side elevation of the same.

a a is `the base-casting, firmly bolted to the deel; or foundation. It has two parallel sides or cheeks, a? c3, and in the space between them is the block b. The said block is channeled at one side for the rope lying between the block and the similarly-channeled side cheek a3.

c c are links connecting the block b with the cheek ai, and c2 c2 are levers or toggles or inclined legs mounted so that one end of each is in recesses in the cheek a2, the other end of each being in recesses in the back of the block b. The parts are so arranged that a move ment of the block to the one side will cause the space between it and the cheek a? to be increased, so that a rope held between the two will be able to run more freely. On the other hand, a movement ot the block in the other direction, which will be the direction in which the rope tends to run, will decrease the space between the said block and the cheek ai,

and consequently the rope will become moreA tightly ni pped.

To the block b a screwed rod, d, is attached, the said rod passing at its other end through the casting a, and being there provided with a wheel and screw-nut, d2, working in a block mounted on trunnions, so that by rotating this nut in one or the other direction the block b mayl be moved longitudinally and horizontally in one direction or the other, toward or away from the rope, so as either to release it or to grip it between the block b and Ihe attachment of the rod d to the block is slotted, so as to give a quick movement of the block independently of the screw.

l' do not limit myself to the precise mode shown of giving motion to the block b, nor to its being in a horizontal position. For small ropes I may use a lever in place of the screw for moving the block b.

I claim- The casing a, provided with cheeks a2 a,

in Combination With the bleek b, the links o,

connecting the block to the easing, the inclined togges or levers c2, interposed between the block and the cheek a2, and means, sub- 5 stantially as described, for moving the block,

theseparts being constructed and arranged together as hereinbefore set forth.

'In testimony whereof I have signed my name i to this specification in the presence of two sub-l scribing witnesses.
